A push-pull set with the loco at the rear is arguably more risky than a MU set, because if the front part derails or hits something it will decelerate rapidly and the momentum of the loco sets up a compressive force through the train. However, as stated by others, these types of accident are very rare and the consequences of each are down to a wide range of essentially random factors.
I always sit at the back of a train in case of accidents. This just blows that theory right out of the water!!
